Discussion:Collected in flower October to July, and in fruit February to September.This variety is very widespread throughout the cerrados of the Planalto of Brazil, and appears to have considerable success in disturbed habitats, such as the roadsides of northern Minas Gerais between Salinas and Diamantina, and some areas cleared for building in the cerrado of the Universidade de Brasilia. There is also considerable variation in leaf size and shape in this variety; individuals with larger less rugose leaves are found in the Distrito Federal and southern Minas Gerais near Belo Horizonte, where B. malifolia is sympatric with B. variabilis, which has large non-rugose leaves. It is possible that some gene flow between these two species is occurring in these areas (e.g., Gates 414, 415). In northern Minas Gerais and Bahia, var. malifolia exhibits characters typical of var. appressa, and has leaves which are not rugose and with appressed pubescence on the upper epidemis.
